With `string_span` having been deprecated (https://github.com/microsoft/GSL/pull/931, https://github.com/microsoft/GSL/pull/945) and removed (https://github.com/microsoft/GSL/pull/1074), the header `<gsl/string_span>` now only contains the definitions for the `zstring` family. Update the name accordingly from `<gsl/string_span>` to `<gsl/zstring>`. The old header is now deprecated and should no longer be used and will be removed in some future release.
